Objective To investigate the incidences of anxiety and depressive symptoms among patients with intrauterine adhesions (IUA) managed by day surgery model, and explore their influential factors. Methods Convenience sampling was used to select patients who underwent day surgery at West China Second University Hospital, Sichuan University between January 2021 and December 2022. General information questionnaire and Hospital Anxiety and Depression Scale were used to assess the socio-demographic data and anxiety and depressive symptoms of the participants. Logistic regression was used to analyze the influential factors of anxiety and depressive symptoms. Results A total of 1100 patients were included. The incidence of anxiety and depressive were 16.5% (181/1 100) and 16.9% (186/1 100) among patients undergoing day surgery for IUA respectively. Longer waiting days for admission [odds ratio (OR)=1.012, 95% confidence interval (CI) (1.004, 1.020), P=0.004], married [OR=0.547, 95%CI (0.344, 0.869), P=0.011], more times of adhesion separation [OR=0.826, 95%CI (0.691, 0.986), P=0.034], older age [OR=0.947, 95%CI (0.909, 0.987), P=0.010] were influencing factors for anxiety symptoms in patients with IUA. Unemployment [OR=0.504, 95%CI (0.256, 0.994), P=0.048], university or undergraduate education [OR=0.326, 95%CI (0.208, 0.512), P<0.001], and high school or vocational school education [OR=0.532, 95%CI (0.319, 0.888), P=0.016] were the influencing factors for depressive symptoms in patients with IUA. Conclusions There is a high incidence of anxiety and depressive symptoms among patients with IUA under the management of day surgery mode. The influential factors include socio-demographic factors (age, education level, marital status and occupation) and disease factors (times of adhesion). Medical staff should pay attention to the early screening of mental health status of patients with IUA, and give targeted prevention and treatment measures.
